Idle Speed/Throttle Actuator - Electronic: Testing and Inspection

****Some values in these diagnostic procedures are incorrect, refer to the following 2 tables for updated values or to TSB - 03-36-024 for updated values****














CIRCUIT DIAGRAM

The MIL is ON or the DTC is displayed on the HI-SCAN under the following conditions:

- When the primary voltage side in ECM is in short or open circuit.
- The ignition closed loop control in ECM is out of order.
- Open or short circuit is observed in idle air control system when ignition switch is turned on.





USING HI-SCAN








HARNESS INSPECTION PROCEDURE





ACTUATOR INSPECTION
1. Disconnect the connector at the idle speed control actuator.
2. Measure the resistance between terminals.

Standard value
Terminal 1 and 2 16.6-18.6 Ohm
Terminal 1 and 3 14.5-16.5 Ohm [at 20 °C (68 °F)]

3. Connector the connector to the idle speed control actuator
